1) 6-2у = 8-3у 6-8 = -3у +2у -2 = -у у=2 2) 15х+3=10х- 12 5х = -15 х=-3 3) -5х-11= -6х-12 х=-1 4) 3х+5 = 8х-15 20 = 5х х=4 5) 5(х+3) = 27+3х 5х + 15 = 27 + 3х 2х = 12 х+6 6) 3у + 4 - 2у = 6 у = 2 7) 5у - 13 - у = у+14 3у = 27 у = 9 8) 3 ( 2х - 4) -2(х+3) = -2 6х - 12  - 2х - 6 + 2 = 0 4х = 16 х=4 9) 4у - 3 = 2(7-у) + 1 4у - 3 = 14 - 2у + 1 6у = 18 у=3
